It's a false flag. The mastermind is the same who activated 911. Whatever they change the colour of their puppet tools, the purpose is the same - to grip more power and money from the people through false flag terror attack. Including this one - to hit the opposing political power.

Norway Terror Attacks a False Flag
More Than One Shooter on Island; Oslo Bomb Drill Just Concluded; Was It NATO??s Revenge for Norway??s Decision to Stop Bombing Libya?
by Webster Tarpley

Washington DC, July 24, 2011 ?? The tragic terror attacks in Norway display a number of the telltale signs of a false flag provocation. It is reported that, although the world media are attempting to focus on Anders Behring Breivik as a lone assassin in the tradition of Lee Harvey Oswald, many eyewitnesses agree that a second shooter was active in the massacre at the Utøya summer youth camp outside of Oslo.

It has also come to light that a special police unit had been conducting a drill or exercise in downtown Oslo which involved the detonation of bombs ?? exactly what caused the bloodshed a few hundred meters away little more than 48 hours later. Further research reveals that United States intelligence agencies had been conducting a large-scale program of recruiting retired Norwegian police officers with the alleged purpose of conducting surveillance inside the country. This program, known as SIMAS Surveillance Detection Units, provided a perfect vehicle for the penetration and subversion of the Norwegian police by NATO.

A motive for the attack is also present: as part of its attempt to mount an independent foreign policy, including the imminent diplomatic recognition of a Palestinian state as part of a general rapprochement with the Arab world, Norway was leading the smaller NATO states in dropping out of the imperialist aggressor coalition currently bombing Libya. Norway was scheduled to stop all bombing and other sorties against the Gaddafi forces as out of August 1 at the latest.
Finally, the CIA limited hangout operation known as Wikileaks has already furnished a prefabricated off-the-shelf case for incompetence and malfeasance against the current Norwegian government that is doing all these things ?? in the form of a series of real or doctored dispatches which document the alleged negligence of this government in dealing with the terrorist threat, all in the view of US State Department officials.
